[ECOS] What is Newlib actually used for?

[Hans Rosenfeld <rosenfeld at grumpf dot hope-2000 dot org>]

I'm wondering what use eCos actually makes of Newlib.

The Newlib libary is used when building the GCC part of the toolchain,
as far as I understand libsupc++ uses it. This seems to be the reason
for the undefined references to __impure_ptr in this library, as a part
of it uses stdio functions for printing some kind of error message.
Stdin and the like are defined by Newlib headers as members of a struct
located at __impure_ptr.

I think eCos never actually uses any Newlib code, so wouldn't a
libsupc++ compiled with Newlib headers cause lots of problems when it's
linked against eCos libraries?

I don't quite understand whats the point of using Newlib and how this is
supposed to work at all. I hope someone can enlighten me about this :)
